I recently reserved (and pre-paid for) a four door Ford Focus at an airport. On arrival I was presented with a two door VW Beetle which was completely unsuitable for what I had to do. I was told that the only other car they had was a Toyota Corolla and that would be a charged-for upgrade. I didn't really have a choice at that time and accepted it. On complaining to Avis later I was basically told, "tough, you accepted the charge". Has anybody else had this kind of experience? And this kind of response from Avis? I don't intend to rent from them again.
